Stunt, there is also a problem with the hoses getting tangled inside the tank near the sending unit. When this happens, the gauge may not read full when the tank is indeed full. I cannot tell from your post if this is your problem or not... This is the problem with my boxster and I am having my mechanic work on it to simply put plastic tie wraps around the hoses to keep them from getting in the way.

My mechanic moonlights out of his home garage, but during the day he works at a dealership. He tells me that people come in with gas gauge problems all the time and it's usually something he fixes with a tie wrap in an hour or so... but the service attendant charges the customer for 4-6 hours of labor to "remove and adjust" something, just because the rate book says that's what should be charged.

I've asked this before at renntech.com. The fuel tank opening is located under the batt. You need to remove the batt and the plate underneath it. You should be able to see it once you've done that. This is only to access the fuel tank opening where the fuel pump is though..... not to remove the entire fuel tank.

do you have scheme for opening the tank and the level indicator, sorry for the english

Hello all!

This is my first post. I just purchased (6/10) a Rainforest Green '01. I'm having a problem with my fuel gauge and putting fuel in the car. When I first purchased the car, the gauge was at 1/4 tank. I tried to put fuel in and it kicked off after two gallons and then wouldn't take fuel at all. The pump just kept shutting off. So I figured it was full and the gauge was off. I drove about 125 miles and it ran out of gas on the PA turnpike! I put a gallon of fuel in and it started right up. I went to the pump and was only able to put another 3.25 gallons in. This means the car ran out of fuel with over 10 gallons in the tank? Is there a problem with the pick-up tube?
I actually have the receipts from the past owner and the trouble with putting fuel in the car has been addressed twice before. They fixed a crimped vent tube, realigned the fuel filler neck. They also pulled out the fuel pump and reinstalled.

Anyone else have this problem or can shed some light as to what the solution is?

Rainforest, I say take it back to the place that did this work and ask them to fix it under warranty. I would imagine the problem lies in a vent tube blockage... the tank can hold 16 or more gallons of fuel and would have no blockage unless the vent tube was clogged.

If the vent tube has become crushed again and they won't do it under warranty, you'll have to get to the bottom of whatever is crushing that tube.

In the mean time, I'd try filling up, waiting ten minutes with the cap off and try filling up some more. You might be able to fill the tank this way, a little at a time.

What a very odd problem. Do come back to this thread to tell us what you discovered as the root cause and what parts were replaced and how much it cost.
